The chimes of the 125-year-old Central High School clock tower fell silent last week when one of the clock’s gears failed. A new gear is being made and should be in place within about six weeks, according to Dave Spooner, manager of facilities for Duluth Public Schools.

“We’ve got the clock apart and we’re in the process of having another gear made,” Spooner said. “It’s not something you can buy, you have to have them made. … It’s just a failure of an old part.”

Central High School opened in 1892, built with a clock tower that rises 230 feet. A new Central High School opened in 1971, and the original building was converted into the school district’s administrative offices. The building has since been known as the Central Administration Building or “Historic Old Central.”
